Tohatsu JIS Standard springs were developed by using noncircular wire and have been standardized by Japanese criterion. Tohatsu springs have been made for high deflection and Tohatsu α Resin guide was invested in and normalized to aid the primary lifespan of springs. Then, ISO STANDARD on the basis of ISO 10243 has been adopted in our production machinery for press machinery used extensively throughout the world to make sure the spring in a best quality. This series has been carefully picked with sizes that are designed to match assorted production machinery used in various industries worldwide, precision manufactured for high strength and durability.
We standardized the springs by adopting cross section materials for the first time in Japan. Tohatsu JIS standard was created using those skills. It can gain higher loads in smaller spaces than round coil springs.
The standards established as criteria for Tohatsu JIS Standard Springs are the Japanese Industrial Standard JIS B 5012:2008 (Coiled helical spring for press dies), Japan Metal Stamping Association standards, and Japan Die & Mold Industry Association standard
AI-100W, AE-100 and AE-100 Doubled
This filter allows for effective filtering of tars, soot’s, rusts, and etc. produced in high temperature oven to prevent fouling of product surface.This filter made of special synthetic fibers has enough durability at high temperature.The filter is easy in handling as distinguished from glass fibers which may be broken and airborned when replacing the filtering media.AI-100W applicable for 180 ̊C – 240 ̊C AE-100 and AE-100 Doubled applicable for less than 180 ̊C
Tohatsu Springs used with high deflection
These type of Tohatsu spring have been made with incredibly varied.The Tohatsu springs used with high deflection can gained a high reputation in plastic mold coils.We can classify to three series for this type of spring which are TR,TY and TU.TR and TY series are able to gain 50% in flexure at free length,while for the TU series,it can go until 65% flexure at free length.
CHARACTERISTICS TR & TY
SRX is the product with special blending method of various rubbers. It is resistant to large deflection (35%) and high load. Permanent set is limited. It is very cost effective compared to coil springs or urethane springs.
PA/350 HL and PA/305 HL
This filter allows for removing almost all dust suspended in air, especially visible coarse particle (more than 10µm) to eliminate the painting troubles.
PA/350HL and PA/305HL are the most suitable filtering media for painting booth.
PA/350HL has sticking properties to prevent of dust break-through.
This disposable type filter is best suited for outdoor air filtration.
It is recommended to use FR-585 for automatic roll air filter (VMR) in respect of running cost.
This filter is very effective to collect sandy dust, as sticking oil is applied to increase dust collection arrestance.
FR-585 is available for panel type.
FR-585 is non-halogen filter. Dioxin will not be brought by incinerating FR-585.
